minutes. Place container or gelatine in hot water.
Stir until dissolved.
In a
large chilled bowl, whisk milk until frothy. Beat in
gelatine, lemon rind, juice and sweetener. The
dessert should taste lemony -- add more juice and
rind if necessary.
Pour
into a serving bowl. Refrigerate until set. To
serve, arrange kiwis decoratively on top of souffle.
